smesh User's Guide
''smesh'' is a general purpose, interactive, 2D unstructured mesh generator based on Overture. It supports three kinds of mesh generation techniques: structured patches with transfinite interpolation (TFI); unstructured triangles based on an advancing front technique; and a Cartesian cutcell/triangle hybrid method. Meshes are generated in a generalized ''multi-block'' manner where each ''block'', or region, can be one of the three mesh types. Geometry definitions can be created interactively by placing points and interpolating curves. Spacing information is provided by both the curve discretization (which can be stretched) and a user specified preferred grid spacing for a region. A mesh optimization procedure is available for the non-TFI regions for mesh quality improvement. Each mesh region is given an unique identifier and an optional string name. Meshes are exported to a modified ''ingrid'' format including mesh region identifiers and names. Facilities for command scripting and batch running are available.
